It turns out that when capable designers are given real constraints for real products they can end up creating great results. In Apple’s case, groundbreaking products like the iMac, the iPod and the iPhone. Constraints have a wonderful way of focusing the mind on the fundamentals, whereas concept products can often have the opposite affect.
Concept products are like essays, musings in 3D. They are incomplete promises. Shipping products, by contrast, are brutally honest deliveries. You get what’s delivered. They live and die by their own design constraints. To the extent they are successful, they do advance the art and science of design and manufacturing by exposing the balance between fantasy and capability.
